> Ranger should provide configuration to have do hdfs audit file roll over at
> absolute time. Currently parameter
> "xasecure.audit.destination.hdfs.file.rollover.sec" is used for rollover and
> the files are closed on relative time using this value from the start of the
> component. Instead we provide
> "xasecure.audit.destination.hdfs.file.rollover.period" which take time period
> with suffix -"m" - minutes, "h" - hours , "d" - days , "w" - weeks, "M" -
> month, "y" -years.
> eg.
> if xasecure.audit.destination.hdfs.file.rollover.period - 1d - ranger audit
> file in hdfs would be rolled over at 1 day window i.e file will be closed
> exactly at 23:59:59 hour for that day and a new file will be opened for
> 00:00:00 hour. In this way we have file content which is exactly for that
> time period window in this case 1 day.
> xasecure.audit.destination.hdfs.file.rollover.period - 1d for 1 day rollover
> period
> xasecure.audit.destination.hdfs.file.rollover.period - 2d for 2 day rollover
> period
> xasecure.audit.destination.hdfs.file.rollover.period - 10m for every 10
> minutes rollover period.
> xasecure.audit.destination.hdfs.file.rollover.period - 1w for every week
> rollover window
> xasecure.audit.destination.hdfs.file.rollover.period -1M for one month
> rollover window.
> if this is param is not specified, it uses
> "xasecure.audit.destination.hdfs.file.rollover.sec" to compute the absolute
> window.
> By default this is 1day meaning if both the parameters are not specified the
> rollover window would be 1day.
